C :

#include<stdio.h>
int main()
{
    int i=555555,j;
    for(j=999;j>=100;j--)
        if(i%j==0)
        {
            printf("%d\n",j);
            break;
        }
        return 0;
}

C++ :

#include<iostream>
using namespace std;
int main(){
	int i,a;
	for(i=100;i<=999;i++){
		if(555555%i==0){
			a=i;
		}
	}
	cout<<a;
}

Pascal :

begin
write('777');
end.

Java :

public class Main {
	public static void main(String[] args) {
		
		for(int i = 999; i >= 100 ; i--) {
			
			if(555555 % i == 0 ) {
				
				System.out.println(i);
				break;
				
			}
		}
	}
}

Python :

l = []
ma = 0
for i in range(100, 1000):
    if 555555 % i == 0:
        l.append(i)
ma = max(l)
print(ma)
